Description
Summary:An abstract of a study by C. E. Vonderohe et al about the comparison of antibiotic-free and conventional management on nutrient excretion in swine is presented. Here, Vonderohe et al determine the effects of antibiotic free rearing on nutrient excretion compared to conventional rearing. Previously reported, there was no difference (P > 0.10) in overall growth rate between control and antibiotic free pigs, however there was a greater pig removal rate from the antibiotic free treatment (8.6% vs. 5.7%). No differences were observed between control and antibiotic-free management on the excretion of DM, P, N, and ammonium N (P > 0.10) per kg of carcass weight. Dry matter excretion was 456 and 445 g/kg of carcass weight for antibiotic free and control animals, respectively.
